Carbon Steel Hot Dip Galvanized Half-thread Hexagon Bolt
Hot-dip galvanized half-threaded hexagonal bolt is a hexagonal head bolt with a hot-dip galvanized surface and a half-threaded threaded part. It is characterized by excellent corrosion resistance and strength and is widely used in outdoor and harsh environments.
Hot-dip galvanized half-threaded hexagonal bolt is a fastener that meets international or national standards (such as DIN 931). The bolt is made of high-strength steel and is covered with a uniform and dense zinc layer on the surface after hot-dip galvanizing to enhance corrosion resistance. Its design includes:
- Hexagonal head: convenient for tightening or disassembling with tools such as wrenches.
- Half-thread: part of the smooth rod design is suitable for high-strength connection.
Hot-dip galvanized half-threaded hexagonal bolt is particularly suitable for use in harsh environments and high-strength demand scenarios due to its strong corrosion resistance, including:
- Construction industry: fixing key components in projects such as bridges, steel structures, and highway guardrails.
- Power facilities: fixing outdoor power equipment such as poles and towers.
- Shipbuilding and marine engineering: Suitable for steel structure connections in docks, ports and marine environments.
- Heavy industrial equipment: High-strength connections for heavy industrial equipment such as mining equipment and petrochemical plants.
- Agriculture and infrastructure: Agricultural greenhouse racks, water pipelines and large sheds.
Advantages
1. Excellent corrosion resistance
- The hot-dip galvanized layer can resist long-term exposure to moisture, rain and salt spray in outdoor environments, and its service life can reach decades.
2. Strength and stability
- The semi-threaded design ensures a tight connection while the smooth shaft provides better tensile strength.
3. Economy
- The hot-dip galvanizing treatment is moderately expensive and more cost-effective than other anti-corrosion processes (such as stainless steel).
4. Environmental protection
- The hot-dip galvanizing layer is non-toxic and harmless, and has little impact on the environment.
Limitations
- Rough appearance: Compared with electrogalvanizing, the surface roughness of hot-dip galvanized bolts is slightly higher.
- Reduced thread accuracy: The zinc coating may cause the thread size to increase slightly, so special attention should be paid to the selection of matching nuts.

1.What is the hot-dip galvanizing process?
Hot-dip galvanizing is a surface treatment process that immerses the bolts in molten zinc to form a protective zinc layer. The process includes:
a. Pretreatment: The bolts are cleaned, pickled and treated with a plating agent to remove surface oxides and impurities.
b. Galvanizing: The bolts are immersed in molten zinc liquid at about 450°C, and the zinc reacts with the steel substrate to form an alloy layer.
c. Cooling: The galvanized bolts cool rapidly, and the zinc layer is dense and firm.
2.What is the difference between galvanized and HDG?
Galvanized usually refers to electroplating, creating a thin, smooth zinc layer for light corrosion protection. HDG (Hot-Dip Galvanized) involves dipping steel into molten zinc, forming a thick, rough layer for heavy-duty protection. HDG is more durable and suited for harsh environments.
3.When to use galvanized bolts?
Use galvanized bolts in outdoor, humid, or corrosive environments where strong rust and weather protection are needed, such as in construction, bridges, or marine applications.
